GRIPPING AND SECURING MECHANISM Filed May 20, 1931 Fig.1

502/01 if. A7 U21 0 c/z Patented Aug. 7, 1934 UNITED STATES PATENTOFFICE 1 Claim.

The present invention relates to a gripping and securing mechanism, andmore particularly to a mechanism which is adapted to grip a sheet-likemember and stretch it, and, while holding said sheet-like member in astretched condition, to nail it upon a mounting member.

In the fur trade, after furs have been sewn together to substantiallythe size required for making a garment or other fur article, the furpiece thus formed is moistened on the skin side, and, while still moist,is stretched upon a board or table and is nailed to the board or tablearound the edges of said fur piece. This operation of stretching andsecuring is referred to in the fur trade as nailing.

An object of the present invention is to make an improved and simplifiedgripping and securing mechanism.

In order to attain this object, there is provided, in accordance withone feature of the invention, a stapling mechanism having a jaw membermounted beneath the stapling mechanism and movable to grip a memberadjacent an opening through which a staple is projected.

These and other features of the invention will be more fully brought outin the following description and the accompanying drawing, wherein:

Figure 1 is a view in side elevation of a mechanism embodying thepresent invention, and a sectional view through a board and a portion ofa fur piece gripped by the device.

Figure 2 is a View in perspective of a gripping jaw and handle memberembodied in the device shown in Figure 1.

Figure 3 is a view in front elevation of the device shown in Figure 1.

Figure 4 is a view in side elevation of the body portion of the deviceshown in Figure 1, with the jaw and handle member shown in Figure 2removed therefrom, a portion of a staple storage chamber and handlemember being broken away; and

Figure 5 is a view in front elevation of a staple adapted to be used bythe mechanism illustrated.

Referring to the drawing in detail, the device comprises a staplingmechanism A of a type well known to the art, and the-mechanism of whichit is not deemed necessary to illustrate in detail, as any suitable typeof stapling or pinning mechanism would be suitable provided a grippingjaw could be suitably mounted thereon. The stapling mechanism comprises,broadly, a staple storage chamber 1 adapted to receive a plurality ofstaples, a slidably mounted operating member 2 with a striking knob 3 onthe upper end thereof, so that upon striking the knob, a staple isdriven down below the lower surface of the stapling mechanism. A handle4 is fixedly secured to the stapling mechanism A and a jaw and handlemember 13 is pivotally mounted on the fixed handle 4, as by means of apivot pin 5. The jaw and handle member B comprises a thin, elongated jawportion 6 having teeth '7 at the forward end thereof to provide agripping surface. Side members 8 and 9, fixedly secured to the jawmember 6, comprise a yoke which embraces the handle member 4. A coilspring 11 may be mounted between the handle members 4 and 10 to normallyhold these parts in separation and thereby to pivotally move the yokemember, comprising the members 8 and 9, in a counter-clockwisedirection, as shown in Figure 1, thereby moving the forward end of thejaw member 6 away from the lower surface of the stapling machine.Gripping teeth 12 (see Figure 4) may be provided below a lower face ofthe forward end of the stapling machine to register with the toothedforward portion 7 of the gripping jaw 6. Staples 13 are stored in thestaple storage chamber 1 in a well known manner, and are fed forward bya suitable spring, not shown, in a conventional manner, so that uponstriking the striking knob 3 a staple will be driven downwardly, asillustrated in Figure 1. Upon release of the striking knob 3 a springnot shown will restore it to a normal position, and the spring 14 willautomatically feed another staple into position for driving. I

If the device were used for a less substantial material than fur, forwhich the present mechanism is intended, it might be preferable to facethe forward gripping portion of the jaw 6 with rubber or other suitablematerial and to elimihate the teeth 12, shown in Figure 4. When thusmodified, the device wouldlbe well adapted for the stretching andsecuring of drawing paper and canvas for draftsmans and artists use.

I claim:

In combination with a stapling machine having a vertically actingstriking knob'and a horizontally disposed staple magazine, a memberhaving a yoke portion adapted to-receive said magazine and, tobeconnected thereto, said member having a horizontally disposed handleportion extending rearwardly beyond said magazine, and a jaw memberprovided with a yoke to receive said-handle member therein and pivotallyconnected thereto to have gripping engagement belowsaid magazine, saidsecond yoke having a horizontally disposed portion extending rearwardlybeyond said magazine in vertically spaced relation from said firsthorizontally disposed handle portion.
